D is a hot air conducting pipe which extends upwardly through the bottom of the incubator into the tank D and coiled within the said tank and extended through the side of the incubator and then upwardly. This pipe is preferably protected between the water tank and its lower end, by means of a water containing jacket D the said tank and encircles the pipe D where it contacts with the casing, to protect it from the heat. Fixed to this pipe D at a point adjacent to its lower end is a pipe D upon which is mounted mechanism whereby the amount of heat admitted into the incubator may be regulated, by means of a thermostatic bar, located within the incubator.

Means are provided for admitting thermometers through the casing into proximity to the egg drawers from the outside of the machine as follows:

J designates tubes extended through the casing at points adjacent to the egg drawers.

J 2 are thermometers fixed to rods J 3 which in turn are connected with the stoppers J By this arrangementthe temperatureofeither of the egg drawers may be seen without opening the incubator door, by drawing the thermometers through the tubes by means of its handle.

Kdesignatesalamp of common form placed beneath the end of the pipe D to supply heat to the incubator.

K designates a tube inserted in the top of the oil containing chamber of the lamp, and leading outwardly therefrom. This tube K is for the purpose of allowing inflammable gases generated in the said chamber by the heat of the lamp to escape, thereby adapting filled when burning.

L designates the egg containing drawers which are adapted to slide upon the tracks B and which are composed of longitudinal slats L with spaces between them to allow the free circulation ofair.

L designates a drawer within the drawer L and resting upon its bottom. Its width is such as to allow it to slide within the drawerL and it is slightly shorter than the said drawer, to allowa slight longitudinal movement therein. Formed within this drawer L are a plurality of perforations which are of such a size and shape as to admit an egg and allow it to rest upon the drawer L and at the same time prevent it from passing through the said perforations. The modified inner drawer is formed of heavy paper N supported by longitudinal strips N This latter form of egg drawer may be more cheaply constructed than the former one and the paper serves to prevent shocks and jars to the incubator frame, from injurin g or retarding the growth of embryo chicks.

O designates a plurality of pans for containing water to thereby supply moisture to the which communicates with eggs, by evaporation. the tank D and extend longitudinally thereof.

Having thus described the construction and function of each separate operative part of the incubator in turn, What I claim as my invention, and desire to secure by Letters Patent of the United States, is-- 1. In an incubator, the combination of a suitable protecting case, having a door at each end, a plurality of tracks leading from both ends to the interior and arranged one above the other, a wire netting or its equivalent fixed t0 the interior of the incubator and extended around the sides of each end portion, at a slight distance therefrom and through the central portion thereof to produce a chamber for the circulation of air around the drawers, and to prevent the young chicks from falling oif, a water tank placed on the bottom of each end of the device, means for heating said Water tank, and ventilating tubes extending from the bottom of the incubator upwardly to the approximate top portion of the interior of the incubator, and ventilating tubes extended through the top of the incubator, substantially in the manner set forth and for the purposes stated.

2. In an incubator, the combination of a suitable casing having a door at each end, a plurality of tracks leading from both ends to the interior and arranged one above the other, a wire netting or its equivalent fixed to the interior of the incubator and extended around the sides of each end portion, at a slight distance therefrom and through the central portion thereof to produce a chamber for the circulation of air around the drawers, and to prevent the young chicks from falling off, a water tank placed on the bottom of each end of the device, a pipe coiled within each tank and having its one end extending through the bottom of the incubator and its other end through the side and then upwardly, a pipe extending upwardly through the bottom of the incubator into proximity to the top of its interior between the central wire nettings and a plurality of ventilating tubes extended through the top of the incubator, and means for closing the said tubes, substantially in the manner set forth and for the purposes stated.

3. In an incubator the combination of the following elements, to wit: a casing composed of an outer wall A and an inner wall A with a nonconductor of heat between them, the doors at each end thereof composed of the parts B and B and having the flange E the vertical strips B secured to the inner walls of the incubator for the purposes stated, the tracksB secured to the said vertical strips and extended longitudinally of the incubator, the wire netting 0 extending around the sides and across the central portion of each end as set forth, the ventilating tubes 0 extending through the bottom portion of the casing, the tubes C and 0 extending through the top of These pans rest upon the same, the water tanks D resting on the a bottom of the interior of the incubator, the coiled pipes D within said tanks and opening below the casing to admit heat to the tanks, the water jackets D surrounding portions of said pipes and the lamps K all arranged and combined substantially as and for the purposes stated.

4. An improved incubator composed of the following elements; a suitable double walled casing having a door at each end, a plurality of tracks extending from the ends to the central portion of the incubator and arranged one above the other, suitable ventilating tubes to supply fresh air into the incubator, a hot water tank located in the bottom of each end, a coiled pipe within each tank reaching to the bottom of the incubator through the tank and out at its side, a lamp beneath the lower end of each of the said pipes, a plurality of egg drawers arranged to be placed in each end and located above the other, means substantially as shown for automatically regulating the heat of the interior of the incubator, and the tubes extended through the sides of the incubator whereby a thermometer may be admitted into the egg drawers, arranged and combined substantially as set forth.

5. An improved incubator comprising the casing composed of the outer portion A and the inner portion A with a nonconducting material between them, a door at each end of said casing composed of the parts B and B and having a flange B, the wire nettings O O, the ventilating tubes (3 G and C the tank D having the coiled pipe D arranged therein,

the water containing jacket D surrounding portions. of the pipe D the branch pipe D the damper H adapted to enter the pipe D and cut oi the supply of heat in the incubator, and-means for operating the said damper, a. plurality of tubes J extended through the sides of the incubator in proximity to each egg drawer and aythermometer J 2 fixed to the rod J and a stopper J 4 adapted to be extended through the tubes J into the incubator, a lamp K having a tube K arranged therein as set forth, an egg containing drawer composed of the part L and the part L having perforations L formed therein, all arranged and combined substantially in the manner set forth and for the purposes stated.

6. In an incubator having doors for the admission of egg containing drawers at each of its ends, the combination of a plurality of tracks arranged one above the other, adapted to support egg containing drawers and extended from each end toward the center of the incubator, and wire nettings fixed to the interior of the incubator and extending Y around the sides and inner ends of the egg containing drawers at a slight distance from the sides of the incubator to provide a space for the circulation of air and heat around the egg containing drawers and to prevent young chicks from falling ofi of the egg drawers, substantially as set forth.
